Description
Technical Field
The utility model relates to a master die technical field specifically is a master die chamfer.
Background
The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".
The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level;
the traditional die is quite inconvenient in chamfering processing and poor in chamfering forming effect, and therefore the inventor synthesizes various factors and provides a main die chamfering method.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a master mode chamfer to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
a main die chamfering comprises a main die shell, wherein a main die upper core is sleeved at one end in the main die shell, a product is sleeved in the main die upper core, and die cavities at two ends of the main die upper core are provided with a head C angle corresponding to the product; and a push pipe is arranged in the main mould shell, one end of the push pipe is abutted against a product, and the other end of the push pipe is sleeved on a push pipe base arranged in the main mould shell.
The state before molding requires that the blank is completely sunk into the upper core of the main mold before molding, so as to prevent mold connecting marks or burrs on the rod part after the product is molded; the product state is formed, and when the kernel on the main die is punched, the C angle at the head part of the product can be completely formed;
as a further aspect of the present invention: a strong spring is sleeved outside the push rod in the main mould shell, one end of the strong spring is abutted to the upper core of the main mould, and the other end of the strong spring is abutted to the push pipe rear seat, so that material returning after punch forming is facilitated.
As a further aspect of the present invention: a limiting ring is arranged in the main mould shell corresponding to the outer side of the strong spring; in the stamping process, when the upper core of the main die reaches the limiting ring, the C angle at the head part of the product can be completely formed, so that the chamfer angle can be conveniently formed.
As a further aspect of the present invention: the main mould shell is provided with a rear cushion block corresponding to the outer end of the push pipe base.
As a further aspect of the present invention: an exhaust groove is formed in the side wall of the kernel on the main die and used for exhausting in the stamping process, and the forming effect is improved.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model provides a main mould chamfer, the state before the shaping requires that the blank must be completely sunk into the upper core of the main mould before the shaping, so as to prevent the rod part from having mould connecting marks or burrs after the product is shaped; and the product is molded, and the C angle at the head part of the product can be completely molded when the upper core of the main mold reaches the limiting ring.
